Question

A child visited a doctor for a sore throat without fever symptoms. They recently received the flu vaccine and took sugar pills. Blood tests showed an abnormally low percentage of neutrophils, diagnosing granulocytopenia. The parents were confused and wanted to know the causes and treatment methods of granulocytopenia.

Answer

Granulocytopenia can be caused by various factors, including drug reactions, chemical poisoning, ionizing radiation, infections (especially viral infections), or immune diseases. Sometimes, the cause may be unknown. Severe granulocytopenia may be accompanied by toxic encephalopathy or central nervous system infection, leading to headaches, nausea, vomiting, consciousness impairment, and even coma. The key to treating granulocytopenia is to actively seek and address the underlying cause. It is recommended to closely cooperate with doctors for necessary examinations and treatments.
